||
| ### From previous meeting(s) | ||
|
|
||
| - [x] (HV) `-dev` vs. `-devel` | ||
| - came up in boost unification, current PR uses the latter based on Isuru's [rationale](https://github.com/conda-forge/boost-feedstock/pull/164#issuecomment-1681583116) | ||
| - matches Anaconda naming & CDTs, does not match recent CUDA feedstocks, tangentially related to distro discussion (RHEL vs. Debian). We should try to choose one. | ||
| - JRG: [Our own data](https://github.com/conda-forge/boost-feedstock/pull/164#issuecomment-1691100805) | ||
| - [x] (HV) Branch deletion policy? | ||
| - I'd [suggest](https://github.com/conda-forge/conda-forge.github.io/issues/1972) to delete dead branches on feedstocks (e.g. long-EOL maintenance branches), and keep history as a git tag on the feedstock. Thoughts? | ||
| - MRB: Historic norm is to leave this to feedstock maintainers. | ||
| - JRG: if we go this way, make it happen via admin-requests, not through UI with no papertrail (automation for the win!) | ||
|

||
| ### Your `__new__()` agenda items | ||
|
|
||
| - [x] (HV) Yearly python releases vs. 5 year upstream support | ||
| - Releases moved closer together due to PEP602, 3.8 still has one full year before its EOL when we start with 3.12 migration ([details](https://github.com/conda-forge/conda-forge.github.io/issues/2004#issuecomment-1717526948)). | ||
| - Generally: Do we prefer 5 CPython builds, or are we fine with dropping support for `v3.{N-4}` one year before its EOL? | ||
| - Jannis: Look at https://github.com/ContinuumIO/anaconda-package-data/issues/41 again | ||
| - MRB: conclusion "we'll make a best-effort committment to all 5 python versions but individual feedstock manitainers may remove older versions at their discretion." | ||
|
|
||
| - [x] (IF) MinGW with UCRT64 toolchain and updated M2 | ||
| - Binary repackage of MSYS2 packages | ||
| (for build only. No linking with downstreams) | ||
| - Binary repackage of `libgcc, libwinpthread` | ||
| - Getting rid of `m2w64-` packages | ||
| - Can we use MSVC/VisualStudio built packages? | ||
| - Are there any that we use with C++ dependencies? | ||
| - Current use is limited to https://gist.github.com/isuruf/d24ebbfaf06318beb992349c90e61ca0 | ||
| - MSYS2 bug: `$(cygpath -w $(cygpath -u $CONDA_PREFIX/Library/bin)) = $CONDA_PREFIX/Library/usr/bin` | ||
| - Get more storage on anaconda.org/isuruf | ||
| - Jannis: I'll ask at Anaconda, how much do you need? | ||
| - 2GB | ||
|
|
||
| - [X] (SC) Emscripten-wasm-32 builds on conda-forge | ||
| - Presentation of emscripten-forge by Thorsten Beier | ||
| - Presentation of use cases | ||
| - Potential CFEP opening | ||
| - Questions: | ||
| - Use CMake directly instead of em-make (?) | ||
| - Compiler ABI incompatibilities might make it hard to have global migrations. | ||
| - Support needed at conda-index & anaconda.org: add issue in conda/infrastructure. | ||
| - We should start an issue in conda-forge/conda-forge.github.io | ||
|
|
||
|
|
||
| ### Pushed to next meeting | ||
|
|
||
| - [ ] (JK) NumPy 2.0 planning | ||
| - https://github.com/conda-forge/conda-forge.github.io/issues/1997 | ||
| - https://github.com/conda-forge/conda-forge-repodata-patches-feedstock/issues/516 | ||
| - HV: Should be possible to only build against 2.x, result [will be](https://githubx.com/conda-forge/conda-forge-pinning-feedstock/issues/4816#issuecomment-1717038980) ABI-compatible with 1.2x | ||
| - IF: It will **not** be ABI compatible if the package author changes | ||
| `NPY_TARGET_VERSION`. Need ways to ensure that it does not happen. | ||
| - [ ] (JRG) Post-mortem on the [Windows upload issue](https://github.com/conda-forge/status/issues/157) introduced in conda-smithy 3.26 (now fixed) | ||
|
|
||
| - [ ] (JL) FYI the creation of a conda "build tools" team under conda governancy policy (still federated until team figures out team charter) for conda-build and hopefully other build tools, welcome to join: | ||
| - [ ] https://github.com/conda/conda-build/issues/4698 | ||
